Abenyo, I went through that too. Until my sister let me keep her five boys each time she had one. Boy did she and her Hubby take advantage of my maternal instincts every chance they got!
However, you need to see what kind of support system you'll have in place.
It's hard on married couples working and raising kids, so equally on single parents.
A good support system is paramount, IMO. A trusted friend or relative to keep your child during the day while you work is a good start. Especially during the child's infancy. I would hate to put a 6 week old in a regular daycare. My Mom worked in one and had horror stories about neglect. She reported and quit. Anyway, my Mother was around for my Sister. Her children didnt go to daycare until they were walking, talking and potty trained. If anyone's mistreating her child, she wants him to be able to say something to her about it, infants cant. She and her Hubby agreed for peace of mind, it would be Grandma's first, then Daycare. Also, cut down on the cost of childcare. My Sister then found a certified home daycare by recommendation that each one of her boys flurished in. I mean this lady had them prepared for when they began to attend school at age four.
Next, you're going to be exhausted and you'll need someone to CARE FOR YOU sometimes. I do remember, that my Sister and her Hubby weren't married on their first kid. She was at home with us (grown! LOL!) Anyway, some days she'd be super exhausted from work, parenting, etc. She always says how much she appreciated when we'd come in and entertain the baby, feed him or get him ready for bed,while she did something else or simply took a breather.
It's important that you have people around you that won't get worried out with ya, that will support you emotionally and help you and your child out at times.
Make sure that you can afford quality childcare with someone or some place that gives you a little peace of mind during the day.
Do you have a job that is flexible enough to support your new role as parent. Where will your child go if anything happens to you?
There's a lot to consider when adopting or birthing a child as a single parent. This is a good time to have friends about to get feedback and use as a sounding board. This way, your decision will not be simply based on your present emotions. Good luck!
